Threading & Tapping Services — Code 1903.1.0019 | Vinahardware

Overview
Vinahardware’s Threading & Tapping process (Code 1903.1.0019) delivers comprehensive thread-making capabilities for internal and external threads across a wide range of parts and applications. Services include CNC tapping (through and blind holes), multi-spindle tapping for high-volume runs, thread rolling for external threads, thread grinding for precision screws and shafts, thread repair (inserts/Helicoil), and secondary operations such as drilling, reaming and finishing.

Equipment & Capabilities

• CNC machining centers with tapping heads and automatic tool changers.

• Dedicated automatic and multi-spindle tapping machines for high-volume production.

• Thread rolling machines for cold-formed external threads (improved fatigue strength and surface finish).

• Thread grinding machines for high-precision threads and micro screws.

• Tooling and fixtures produced in-house; plug & ring gauges, optical comparators and CMM for inspection.

Standards & Materials

• Supports Metric (ISO), UNC/UNF, BSP, NPT and custom thread profiles.

• Materials: carbon steels, alloy steels, stainless steels (SUS304/316), aluminum, brass and engineering plastics.

• Thread ranges: commonly M1.6 up to M48 and equivalent imperial sizes; deep-hole tapping supported for blind holes.

Quality & Inspection

• Tolerance and fit per ISO/ANSI standards; inspection by plug & ring gauges, thread micrometers, optical comparator and CMM.

• Batch QC reporting and traceability provided on request. For critical components, full measurement reports and sample images are supplied.

Process Flow

1. Customer submits drawings (DXF/STEP) and thread list.

2. Vinahardware proposes the optimal method (cut tapping vs. rolling), tooling and fixture plan.

3. Sample run and approval.

4. Production with scheduled in-process inspection and tool life monitoring.

5. Final finishing (cleaning, coating, inserts) and packing.

Applications

• Fasteners and fittings for furniture, automotive brackets, industrial machinery, electronic enclosures, and medical devices.
